Rafael,
have just read through this thread - lots of pretty sound advice. I am also biggish ( 6'2" & 220lbs) and have been through various phases of getting a good shortboard. Anything from 6'5" x 20x2 5/8 to 7'0" x 20 x2 7/8. Now I have
My problems ( if you can really call lack of the pefect board a problem) have been solved by some good advice and shaping from Rex Marechal who is a local shaper & friend. He watched me in the water and then offered some input on my next board - just as an aside. I took him up on the advice and have been really pleased since.
Now I have:
6'10" x 22 x 2 5/8 with a flat deck, swallow tail and flyers. The bottom curves and rail shapes are hi performance - not just big eggy boxes. FCS plastic fins for 2 -3 f surf, carbons for 4 ft +.
7"5" x 21 x 2 3/4 flat deck & rounded pin tail for 4 - 8 ft surf.
Really happy with the results and now just concentrate on surfing - not so much about getting the right board. Anyway, just a footnote to everyone elses comments but I can really identify with your quest to surf on boards that match your physique & aspirations.
